37" KO3 Cs are out? .... Nope

[Ratbert]

I was under the impression that 37x12.50R17/C KO3s weren't going to be out until next year, but they're out now? https://www.discounttire.com/buy-tires/bfgoodrich-all-terrain-t-a-ko3/p/157631

66 pounds seems relatively light too, but, of course, it's a C.

Edit: May 2026. With reviews, which I'm guessing are for other sizes.

Isn't C-Load range ideal? Much softer tire for better ride quality

On road, yes. Bit risky in the rocks. I did this to both 37" KO2 Ds and 35" KO2 Es:

@Ratbert -

A rating of 4.6 stars based on 535 reviews for a tire that is not yet fully in the market? Did Discount Tires and their customers participate in a testing program or is this a bit of shenanigans on their part?

Crap. Didn't see that.

Ratings on stores like this are typically a random assortment of people chiming in.

The ratings at Discount Tire are for all sizes of the same tire. They aren't broken up by size. The KO3 has been out for a while which means there is some legitimate experience with them.

However, several reviewers just post up initial impressions with almost no time on the tires. And that's less than useful.

I went out to the KO3 road map just the other day to see if a load range D in 37x12.5 would be coming. I didn't see anything forecasted which is a little disappointing.

I'm at 52K/4 years on my KO2s LRD Ds and am starting to shop for the next set. I need to crawl under the Jeep and see if I can find the date code. They could be closer to 5-6 years in age and I could rationalize an early replacement.

Mine (same specs) are getting pretty sketchy at 45k miles. I'll probably replace them with Mickey Thompson ATs.

What are the 37s on the Raptor with the big tire factory package? I thought they were a lightweight KO2.

Load range C

Load range C

That's what I thought, so then there should be some of them out there. But you might have to purchase through a Ford dealer?

What kind of conditions are you seeing sketchy performance? Mine just seem to be loud.

Still KO2s though looking at the 2025 Raptor R at a dealership:

That's possible. It seemed like when the KO3 launched it was only available on new trucks and OEM sizing.

I looked again and the load range F is available now in the KO3 37x12.5. I haven't been able to find what the application is for that size and rating to make it available before D.
